CharacterIn cooperation with the most famous DJs, Ultrasone developed this outstanding pair of professional DJ headphones. Using a heavy-duty 50mm Mylar driver, the closed-back DJ1 PRO provides the most powerful music output in combination with the most advanced technologies. Equipped with MU-Metal shielding these headphones also meet the needs of DJs considering safer hearing aspects. In addition you will find useful accessories in the DJ1 PRO hardcase: one coiled cord (3m), one coiled cord with volume control and stereo/mono switch and a spare pair of speed-switch earpads. The new designed hardbox will ensure a safe transportation and storage.

ULE-technology & PRO designPRO headphones have Ultra Low Emission (ULE) technology with significant benefits for professional users. PRO headphones also have a unique design; the PRO appearance not only distinguishes the professional line but also allows a higher degree of transparency in combination with the spatial sense and understanding, due to more ear anatomy area.

To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal that you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) to reduce the radiation by up to 98% compared to current headphones. The ULE-technology has stood the test of international review and is recommended by technical surveillance organizations. Ultrasone originally developed the ULE-technology for professionals as they spend half of their lives in headphones. But due to grand requests the, ULE-technology has now been integrated in other Ultrasone headphone lines.

S-Logic Natural Surround SoundThrough the S-Logic Natural Surround Sound the usual headphone sound will be moved out of the head into the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived--it's just like being in a live concert. For this new technology, additional equipment is not required. Take a pair of Ultrasone headphones plus your sound device and you will be ready for the 3-dimensional sound enjoyment.

Safer hearingS-Logic does not only create a Natural Surround Sound. S-Logic allows, at the same time, a reduction of sound pressure levels by up to 40% (3-4 dB) for the same loudness sensation. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening. However, Ultrasone generally advises not to listen to music at high volumes to prevent hearing damage.

These cans are solidly built, with rugged joints that have lasted through many gigs. The unscrewable headphone jack is nice, but you might want to get an 1/8" extension cable since it's only about 3 feet as opposed to 6+ feet for the 1/4". The cushion on the headband isn't very soft and can dig into the top of my head if I'm not careful. At around $200 the sound is very very clean and flat, with a smooth, full bass that won't clip. The overall tone is a bit cold compared to slightly cheaper Sonys but the large size and excellent sound insulation definitely save my ears from abuse in a club situation. They're also very nice for producing because of the clean, deep bass. You won't be exaggerating the bass to compensate.If you can get a good deal on these, they're a great pair of cans. If not, you might want to look elsewhere.

I didn't know anything about S logic until I heard the sound of these headphones. You can hear everything that it is going on, descent audio quality and the isolation is incredible. They are very comfortable as well so long gigs will never be a problem again. I like the case too. No cons so far and it doesn't seem there is going to be any !
